Subaru. has developed a cell balancing method for electric vehicles with lithium-ion batteries. The method adjusts the state of charge of each cell based on predicted standing time and capacity ...

When designing, specifying, or purchasing a lithium based rechargeable battery pack, a question that should always come up is cell balancing as it relates to safety and long-life for the battery pack.

Self-discharge is a normally occurring phenomenon in lithium-ion battery cells. A normal cell may have a self-discharge rate of 1% state of charge (SOC) per month. The normal self-discharge rate is ...

This article is part of the TechXchange: EV Battery Management. Every battery chemistry has its tradeoffs, but the tradeoffs with lithium-ion (Li-ion) batteries are more favorable than most. Li-ion ...
